You may want to begin by taking some Electrical Engineering classes and throw in a few Mechanical Engineering courses also.How to design a new plc?
IMHO, if you have to ask that question, you probably shouldn't be asking it in the first place.This is a great example of 'can-do' attitude. This is what they tell us has made America great. Aim high. Shoot first. And so on.
I agree and even if you know it takes a lot of resources to develop a PLC. I know. There isn't a whole lot of difference between a PLC and a motion controller but then think of all the different I/O cards a PLC has that a motion controller doesn't.IMHO, if you have to ask that question, you probably shouldn't be asking it in the first place.
India is working on it.This is what they tell us has made America great.
And that's the sort of thing that is disheartening about projects like this.
I remember a similar 'Open Source PLC' project a few years ago. The lead hardware designer posted to the listserv saying he had to wait until his next disability check came before he could buy another batch of circuit boards, but if somebody wanted to contribute $70 he could do it sooner.
While I admire the attitude and goals, if your development project stalls over a matter of $70, it is profoundly undercapitalized.
